    Is there a recommended minimum thickness for external render, including scratch coat and top coat with roughcast. The guy doing the work on my house must have painted it on!

    Hope you can help?

    Hi RCDD

    Yep. BS5262. Render should be applied in two coats. Recommended thicknesses are base coat no more than 15mm and second coat around 6-10mm. Total thickness therefore anything up to 25mm (1 inch in old money).

    I would add, though, if the guy has just applied a roughcast then this is not a proper render and is usually applied afterwards as a thin coating.

    about 15mm is normal minimum thickness

    Sounds like you`ve been done.The boys are right.Average at least 20/25mm with two coats with roughcast on top of that.

    Cheers Lads, I thought that was the case. Wattsy, I haven't been done yet as he hasn't been paid.

    Cheers
